I booked a three day trip to Venice for me and my partner for February 2014 via Groupon. I then tried to book the holiday and was told by Clearsky that there were no flights available, even though I could go at anytime that month. They said that I could have flights if I was prepared to pay a considerable surcharge. I said I couldn't believe that all flights were already booked for a whole month so they suggested I could go for two days instead of three from London (I live in Scotland).

I then, rather too late, read reviews on this company and found that most other people had the same experience, being asked to pay extra to get what they had already purchased.
